Speciication forming of Letters Patent No. ldi., dated November 23. 1869.

llo all whom -it may concern:

Be it known that I, RUDOLF EICKEMEYER of Yonkers, in the county of Vestchesterand State of New York, have invented certain new and useful Improvements in` Hat-Bouncing Machines; and I do'hereby declareA that the following is a full and correct description there-i of, reference being had to the accompanying drawings, and to the letters of reference thereng n The `first part of my invention relates tothe rotating emery-wheel or pouncing-cyli'nder 5 and consists in an elastic pouncing-cylinder or eniery-wheel formed ot a sleeve or bag of emery-paper or emery-cloth placed upon a wheel, cylinder, cone, or other proper-shaped holder of elastic rubber or equivalent mate rial, and held thereon by the distention of the rubber l holder circuniierentially within the .sleeve of emery or glass'covered paper or cloth.

-Idhedistention may bereffeeted byior'cing the rubber holder upon a taperflathe mandrel, or by compression between. clamping-plates at the ends of the pouncingcylinder, connected and drawn together by a tubular serewzthrou gh theaxis of the rubber holder, the tubular screw being provided with an internal screw to attach it to the lathe-mandrel; but I preferto ,place the rubber holder upon a lathe-mandrel of either taper or cylindrical form, provided with aiiange and a follower, the latter to be screwed upagainst the outer end of the rubberholder, as shown inthe drawings, and here inai'tcr 4more particularly described.-

`lilly improved emery-wheel or pouncing-cyL- inderI has the advantages of aiexible surface,

and great facility in changing the einery or powdered-glass cuttingsurfacc, which, in the operation of pouncing hats, soon becomes guinmed with the size or gum used in stiening the hat-bodies. The flexibility of the surface adapts it to other purposes than pouncing hats, being applicable to grindingv rounded metal surfaces.

My invention further consists in an arrangement of the pouncing-cylinder anda rest or supporting-horn for the hat-body, which can be introduced within the crown to support it against the cutting action of the pouncing-cyliuder during the operation of pouncing, the arrangement being such as to dispense with theuse of a hat-block in pouncing the tips and side crowns of the hats.

My invention further consists in the inode of adjusting the rest or supporting-horn, and also a swiveling feeding apparatus, whereby. the feed-inotion imparted to the hat maybe changed at pleasure during the operation of pouncing to a larger or smaller curve, or a straight line, `as rcquircdby the dili'erent paris ofthe hat-body undergoing the operation ot' pounei n g.-

But, more particularly to describe my invention, I will refer to the accompanying drawings, which represent a machine for pouncing hats which embodies my aforesaid improvements. i

Figure 1 :represents a front elevation of the machine; Fig. 2, a side'elevation; Fig'. 3,21,- plan View of the same; Fig. 4,*detaehcd views of the side elevation and plan )of the adjusta- Vbie part ofthe supporting-Thorn; Eg. 5, seetii" of the improved emery-wheel or pouncing-cylluder; Fig. 6, detached views, side elevation, and plan of a roller substitute for the adjustable supporting-horn shown in Fig. et), Figs/7 and S, plan views of sheet-metal patterns used in cutting out and folding the sleeves of einery-papertor the pouncing-cylinder.

Letter 'a represents a table or bench, on which is placed a lathe-head, b, facing the front of the bench. y

Motion is imparted to the lathe-mandrel lil from a sl1at`te,rbelow the table by a pulley, el', and belt c2c A tubular portion, b2, of the lathe-head projects forward to the front of the table to support the mandrel near the pouncing-cylindcr d, and give room for the rim of the hat when the tip is .pouncing This tubular yportion oil the lathehead is not a necessary feature of the construction, but is preferable, because the ,use of it admits of using a shorter latheliead and lighter mandrel than if the inandrel were unsupportedbeyond thelathebead,from which it must project sutticiently to make room for the hat, as shown in Fig. 2 of the drawings.

Directly under the pouncing-cylinder isa vertical supporting-horn or rest, dl, the upper part of which is hinged to the lower part at dz, andadj usted to the inclination of the pouncing-cylinder by the adjusting-screw (Z3.

For the purpose of readily adjusting the supporting-horn to different sizes of pouncingcyliii ders or varying thicknesses of hat-bodies, it is mounted upon or cast with a horizontal treadle-lever, d4, pivoted at di", and adjusted by the adj usting-screw d5; but any other practical inode of mounting the vertical supporting-horn will answer which will admit of vertical adjustment and leave suiicient spaeebetween it and the lathe-head for the brim of the hat when pouncing the tip, the essential part of the arrangement of the supporting-horn being the space left between it and the lathehead to give room for the brim while it is supporting the tip in the operation of pouncing.

Instead'of the tlat supporting-surface of the supporting-horn, as in the principal figures of the drawings, and in detail in Fig. 4, a rollersupporting surfacesuch as shown in Fi g. 6 iiay be used, being hinged and adjusted in the Saillie 111311111612 rEhe pouncing-cylinder (shown in section at Fi g. 5) is composed of av sleeve of eiuery paper or cloth, e, placed u )on a' conical rubber holder, e, mounted upon a taper-lathe mandrel, e2, between a ange or clamping-plate, e, uponv the lathe-inandrel` and a follower, e, set up by a screw-nut, c5,-upon the end of the lathe-inandrel.. By unserewing the nut the sleeve of emery or glass-covered cloth is loosened, and may be removed and replaced by another.

The sleeves should be made of cloth or paper, covered with powdered glass, emery, or

other suitable cutting-surface, glued to the paper or cloth; and, for convenience in making them, a sheet-metal segmental pattern, of the proper shape for the cone, and similar to Fig. 7, should be used in cutting out the einery paper or cloth, and another sheet-metal pattern, like Fi g. S, should be used in forming the sleeve and gluing the ends together. A proper supply of the conical or cylindrical sleeves being thus made and at hand, the operation of the machine is but momentarily interfered with when necessary to renew the pouncing-surface.

The lower feeding-wheel, g, Fig. 1, isinounted in the forked end g2 of a vertical spindle or .rocking shaft, g3, supported by a step, g, and

bearing g. The upper feeding-wheel, IL, is supported by a bent lever, lt, pivoted at IiP' to a horizontal frame, It, attached to the vertical spindle g3, which carries the lower roller, so that both feed-rollers are supported by and swivel on the saine vertical axis.

The feeding motion is given to the feedvhenls by a bambi', ruiming from a pulley, i, upon the shaft c beneath the table, overa pulley, fiz, Fig. 3, attached to the side of the lower feeding-wheel, the upper feed-wheel being held against the lower by a weight, h4, suspended from an arm of the bent lever h.

'The bent leverh, which holds the upper feedwheel, should be bent outsufiieiently to give rooin for the brim of the hat when the tip is lpouncing.

The feed wheels or rollers feed the hat-body either in a curved or straight line, as they are held in position by the operator, who'takes hold of the handle j for thatpurpose, the handle k being iused to lift the upper feed-wheel from the upper surface of the hat.

Now,it is obviousthat the feeding-wheels being in advance of the pouiiciiig-cylinder and .supporting-horn, lby changing the position of their axis from a position parallel with the axis oi the pouncing-cylinder to a greater or less angle within certain limits the brim and tip of the hat-bodymay be fed under the pouncing-cylinder in required horizontal curves or circles, and the side crown directly, forward,

the direction of the feed being wholly under the control of the operator. y i
